FWIW I dug into the schematics a bit to see if there was a way to get the
DRU-2 to feed into the data input instead of the mic input. If you gnd the PKS
input (packet stand-by line) the mic is muted while the data input remains
active. While easy for an external DVP, the DRU-2 path is hard connected to
the mic at the mute circuit.
Hmm actually there MAY be a way out of that box if you give up some of the DRU
function. I just had another idea about it I need to check out in the
